Method for synchronizing contact information

A method for synchronizing the contact information, which is applied in the synchronization between a wireless exchange device and a communication device. Both the wireless exchange devices and the communication devices have a synchronization software, respectively. The synchronization software allows the wireless exchange device and the communication device to be set as a transmitter or a receiver interchangeably, and it also allows a keyword searching, multiple entries, or the entire database of contact information to be sent from the transmitter to the receiver. In addition, the synchronization software also provides a verification process to ensure the contact information is only sent to the authorized device. Therefore, the receiver can obtain the contact information stored in a contact database of the transmitter, thus achieving the aim of updating the contact databases.
